Mornings with Dave & Jen

From the Daily Mail, here are five bad habits that are actually GOOD for you:

BITING YOUR NAILS helps expose your body to new germs . . . but in very small numbers. That lets your immune system prepare antibodies to fight them without the risk of getting sick.

BURPING protects your body from getting damaged by stomach acid. If you leave the gas inside, it can loosen the muscle that separates your stomach from your esophagus, and allow stomach acid to splash out and cause heartburn.

PASSING GAS prevents you from having a buildup of gas in your intestines which can cause damage . . . or at least a lot of pain.
